>             Project: Flink
>          Issue Type: Improvement
>          Components: Runtime / Coordination
>    Affects Versions: 1.10.0

> Currently {{RegionPartitionReleaseStrategy}} and {{AdaptedRestartPipelinedRegionStrategyNG}} both need to compute distinct pipelined regions, which affects the performance due to the duplicate calculating.
> The best idea that comes to my mind so far is calculating distinct pipelined regions in {{DefaultExecutionTopology}} so that we can remove the duplicate calculating.
